Abstract

1390182 Exhaust gas catalyst JOHNSON MATTHEY & CO Ltd 16 March 1972 [16 March 1971 (2) 17 June 1971 (2) 9 Nov 1971 (2)] 6986/71 6988/71 28391/71 28392/71 52052/71 and 52053/71 Heading B1E [Also in Division F1] An exhaust gas catalyst comprises an inert material impregnated or coated, with a mixture or alloy of platinum, rhodium and a 'base metal' wherein there is 1 to 50 wt% Rh and 0.01-25 wt% base metal of the total metal content. 'Base metal' means any metal other than the platinum group and gold. Specified base metals are Al, Mg, Cr, Mo, W, Mn, Fe, Co, Ni, Ti, V, Th, U, Cu, Ag, Zn, Cd, Hg, In, Tl, Bi, Sn, Pb, Sb, the lanthamides and the actimides. The inert support is suitably a unitary porous refractory compound, e.g. a ceramic material in the form of a corrugated cellular structure or honeycomb. Specified carriers are mullite, zirconmullite, alpha alumina, sillimanite, magnesium silicates, zircon, petalite, spodumene, cordienite and alumino-silicates. The carrier may have a layer of a refractory oxide deposited thereon before deposition of the metals. The Examples describe ceramic honeycombs coated with intermediate layers of alumina and a top layer of an alloy of Pt, Rh and one of Ni, Co, Fe, Cu, Nd or Pb.
